Water Leak Detector Sensor Alarm: Home Water Flooding Monitor Smart Sink Overflow Monitoring Adjustable Wet Moisture Alert Pipe Leakage Drip Detection Warning for Basement Floor

Works great! I have a closet with my AC unit and water heater on top of each other and was told to get one of these after a neighbor had an issue with a leak they didn’t notice and had to spend thousands on repairs due to the water damage caused to the downstairs neighbor. Wouldn’t you know it! A few months later my AC drainage pipe gets clogged and the AC water starts to drip down into the water heater. I have one of those plastic rims under the water heater so most of the water accumulated in there and made the alarm go off. It was sooo loud. It was in the middle of the night and I was in my bedroom on the other side of the apartment with the door closed and I could still hear it! Best purchase ever!

Pretty amazing product. It can be used repeatedly unlike some other products listed. Works by conduction with water and making a circuit between the “terminals?”

I’ve had a 60-gallon reef tank for almost two decades, which means I regularly mix fresh saltwater very other week. I always set a timer to warn me when my salt mix bucket is about to overflow, but sometimes the water fills at an unpredictable rate, and I’ve ended up with mini floods in my kitchen more than once. So, I finally decided to get a water leak sensor. At first, I looked into smart sensors that connect with Apple Home or Samsung SmartThings, but they were pricey ($35+), had non-replaceable batteries, low audio alarm, and had frequent complaints about disconnecting from the system. Instead, I went with a simple, battery-powered water sensor, and I’m so glad I did! This device is not only loud but also incredibly accurate. The moment even a tiny part of its foot touches water, it sets off a piercing alarm (and I mean LOUD. I can hear it from several rooms away). Best of all, it’s a straightforward device with replaceable batteries, and I can even use rechargeables. No complaints whatsoever, and for this price, I can’t recommend it enough!

Works well enough, but it is very quiet. Maybe 75db at most. I had to test it to make sure it would be loud enough to be heard from other parts of the house. Also, no mention of a low battery alarm in the documentation. So I assume I'll have to test it periodically.

Without this alarm, I would have been unaware that my basement was starting to flood two weeks ago. Because it alerted me when it sensed water on the basement floor, I was able to get a utility pump in place quickly and avoid disaster. It is not terribly loud, but loud enough to grab my attention from a distance of twenty feet or so on another floor with the basement door closed. Probably the best $10 I ever spent!

Works as it should. Very well made. Gave me peace of mind

easy to use, and extremely loud, I love this device since we have a 3 story house, and I can hear the buzzer on all floors.

This item warned us about water in bathroom. Good purchase!

Just arrived. I tested it, it does sound when water touches its sensors. Very loud alarm for my apartment, but not sure if it is loud enough if you place it in an American-style house basement. Edit: It has since consistently worked for my leak. Loud alarm every time, good product

It's just what I needed for my basement it works...what more can I say!

Fait très bien le travail mais n’est pas connecté au wifi ou à quoi que ce soit donc il faut être sur place pour entendre sonner. La sonnerie est très forte c’est un avantage

No floods yet. seems quite simple.

I held off on reviewing this as I hadn’t had a water leak yet. Our washer has leaked twice in the past year which was what prompted me to purchase this alarm. Yesterday the alarm sounded when I had a load of laundry in, and sure enough it was leaking water. I was very happy to be able to address the problem quickly without my basement flooding or the water causing any damage.
